Ear Notching System In Thailand

Ear Notch

Surin Farm uses the following picture to train the staff on the ear notch system that is used in Asia. Numbering starts with the upper side of the left ear then rotates around to the right. Close to the tip of the ear is number 3, middle number 9 and bottom number 1. Example: the number 8 would be two notches of 3 (3 + 3 = 6) and two notches of 1 (1 + 1 = 2) for a total of 8. This system allows for a number from 0 to 9,999.
